A physics student stands at the top of a set of bleachers. They drop a basketball and it lands 6 seconds later.
a. How high are the bleachers?
b. How fast was the basketball traveling at the time it landed?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

Unpolarized light of intensity so passes through two sheets of polarizing material whose transmission axes make an angle of 60∘ with each other as shown in the figure. what is the intensity of the transmitted beam, st?

It takes a lot of energy to get the temperature of water to increase and eventually boil because water has a high heat.
